Aldus address -- Sorry about providing the wrong email address for Aldus at the end of the IntelliDraw review last week. I read it from the business card that came with the press information. The manual gives another AppleLink address for IntelliDraw:
Full Screen Quick Look in Snow Leopard
When viewing files in the Finder in Snow Leopard, instead of pressing just the Space bar to enter Quick Look, press Option-Space to display the selected document in full-screen Quick Look, expanding the preview and hiding everything else that would otherwise remain visible.
